Hmm... I agree, the first two are easy enough - in fact the first has been around since at least the 1970s, but wrapped in a different narrative - but that pickle jar has me expending more brain cells that I think are necessary. Bet I'm overthinking it.

John -- that assumes that the amount of money accumulated in the jar is the right amount to pay for a meal. But the premise doesn't lead to that -- it only says that the length of time to fill the jar is when meals are bought. The jar may have well in excess of the amount to pay for the steak, or not enough so that the meal is paid for out of Harold's wallet.

(I was about to write to Adam and Alex with the same argument, but caught myself first.)

There are way too many ambiguities for this to be a definitive puzzle and I had taken into account that the jar may have been filled and refilled a number of times in the three month period but as it required a time frame for the filling and the only time given was the three months, one would have to assume it was filled just once or otherwise the puzzle would be missing a vital piece of information.

All in all the three riddles were interesting, if not too difficult to reach a conclusion as to the answers, and I hope we get more of the same.

I really like his puzzle books, because he provides a level of difficulty for each puzzle which makes it easy to keep the hard ones for a rainy weekend, and a hint, which is sort of a 'half solution' which gives one a second chance to solve the puzzle before giving up. Puzzle #65 is also a magic trick.

These riddles can have multiple solutions.For example, Number One.The wrestler is strong and fit , but very tall - say 7 foot plus, so people offer him a seat so that he can sit down and have a more comfortable train ride.
